Abstract

La présente invention concerne un système de gestion de chaleur comprenant : une ligne de circulation de réfrigérant comprenant un compresseur, un condenseur de refroidissement d'eau, un condenseur de refroidissement d'air, un premier détendeur, un évaporateur, un échangeur de chaleur de réfrigérant et un séparateur gaz/liquide qui évacue uniquement un réfrigérant liquide, et refroidissant un lieu intérieur en faisant circuler un réfrigérant ; une ligne de chauffage destinée à chauffer le lieu intérieur en faisant circuler, à travers le condenseur de refroidissement d'eau, de l'eau de refroidissement qui échange de la chaleur avec le réfrigérant ; et une conduite de refroidissement destinée à refroidir une batterie et un composant électrique en faisant circuler de l'air ou de l'eau de refroidissement qui échange de la chaleur avec le réfrigérant. Par conséquent, la présente invention peut non seulement refroidir et chauffer un véhicule, mais également gérer efficacement la chaleur d'un composant électrique et une batterie dans un véhicule, et peut réduire le nombre de composants constitutifs pour le chauffage et le refroidissement, ce qui permet de produire un système de refroidissement du type à bas prix.
